Hush AI runs on your device's CPU, not a cloud supercomputer. Larger models produce better answers but take longer. If speed matters, try the Swift or Smart tier.

Hush AI uses open-source language models that are capable but not perfect. Responses are AI-generated and may contain errors, especially with math or recent events. Always verify important information.
